lovely-systems

=================================

Simple implementation of [L-Systems](http://en.wikipedia.org/wiki/L-system) in Lua, with examples in LÖVE2D.

Requirements

------------

* Lua >= 5.1 (?)

* LÖVE2D (for the example project)

Running the example project

		love example

Downloading the source

------------

Either with git clone as below or by downloading a zipball of the [latest...](https://github.com/Profan/lovely-systems/archive/master.zip)

		

		git clone https://github.com/Profan/lovely-systems.git

Usage

------------

When testing the example, use your arrow keys to change scale and segment size.

Example of defining a sierpinski triangle, example also already present in example code.

```lua	

local lsystem = require "l-system"

		

initial_state = {state = {'F'}, rules = {['F'] = 'G-F-G', ['G'] = 'F+G+F'} }

fractal = lsystem.nthstep(initial_state, 2) -- recurses twice

		

-- fractal.state now holds: F+G+F-G-F-G-F+G+F, in table form.

```

which in turn can be used to produce: ![Fractal](http://i.imgur.com/iPqtXre.png)

or by increasing the iterations to 8, you can produce: ![BetterFractal](http://i.imgur.com/wR1noEP.png)

another example, a christmas tree! (sort of)
